PLATFORM-SPRING FOR ROAD-VVAGONS.

SPECIFICATION forming part of Letters Patent No. 448,790, dated March 24, 1891.

Application filed October 13, 1890. v

To alt whom. t may concern:

` the city of Cleveland, State of Ohio, have invented certain new and usefulImprovements in Spring-Platforms for Road-lagons where of the following is a specification embodyilig my invention.

The invention consists of the improved devices and combinations of the several parts constituting the complete structure, as hereinafter more t'ully set forth, and as pointed out in the appended claims.

In the drawings, Figure l is a side elevation of a complete road-wagon constructed upon the general plan o t my invention. Fig. 2 is a plan view ofthe front spring-platform.

Fig. 3 is a plan view of the rear springplatform; and Fig. 4 is a front elevation of the lower edge of thebody, axle, and transverse spring.

These spring-platforms are separately constructed, and either may be employed to support one end of the body, while some other well-known means may'be applied to support the opposite end.

My invention has for its object the oblique arrangement of side springs in contradistinc* tion to those that are placed in positions parallel to each other, and said oblique springs being re-entorced by a transverse spring or springs having their opposite ends suspend ed from or sustained by the axle at or near its opposite shoulders upon suitable shackle or pivotal connections therewith, either by a direct connection with the body of the axle or pivotally engaging the terminal ends of the oblique side springs. Said transverse sprin gsupport may be carried immediately above and over the axle or on either or both sides of the latter, or an elliptic spring transversely arranged and supported upon the .center of the axle in the usual way may be substituted wit-hout departing from the spirit and pur-` pose of this part ot' my invention, since a single or duplex spring may be employed according to the weight the vehicle is designed to carry.

serial no. 368,054. v(no modem point to the rear of the axle and suspending it from the bot-toni of the body.

A suitable frame-work adapted to connect the elevated center-portion of the transverse spring and the terminal rear ends of the side springs A A is pivotaliy supported by the king-bolt coupling N, connected to the bottom traine of the body and forwardly sustained by said transverse spring. Said frame and king-bolt coupling or fifth-Wheel device may be of any appropriate or well-known construction adapted to the purpose. elevated center portion of` said transverse spring is provided with a friction or roller hearing adapted to sustain the front end of the body, the bottom frame of which carries a segment-plate G "(seen in dotted lines, Fig. 2) of such requisite curvature as will admit of its riding upon said roller or a corresponding segment-bearing connected to the spring-frame when turning the vehicle. The side springs A A are obliquely extended from Vthe spring-frame or iitth-wheel device to the rying the steps suspended from the sides of' the body in place of being attached to the spring-franie- It but a single transverse spring A is employed its terminal ends are preferably suspended upon a pivoted or shackle bearing engaging the front ends of the side springs A A; but it duplex springs are applied, as indicated in dotted lines, Figs. l, 2, and 3, they are preferably suspended upon pivotal bearings connected to the axle independent ot' any direct connection with the side springs. The rear ends of the oblique side springs A A may be connected to the spring-frame or `tifth-wheel device engaging the king-bolt N in any well-known manner that will attord a proper support and se cure their requisite action. The center bar E, extending from the transverse spring rearwardly and engaging the king-bolt, constitutes a part of the spring-frame carried by said king-bolt. In this instance, and as seen in Figs. l and 2, the frontend of said central IOO bar E is adapted to carry the roller F, on which rides the segment-plate G.

In the rear spring-platform (seen in l1`ig. 3) the arrangement and combination of the side and transverse springs A A and A with the axle are the same as described in the front platform, Fig. ln this instance, preferably, two cross supports or barsJ and J are interposed between the inner ends of the side springs and the body. 'lhe cross-bar J is preferably secured to the bottom center sill of the body by thebracket lx. (See Fig. l.) These interposed cross-bars serve the doublepurpose of a support for the inner ends of the side springs and as a means to regulate the hang of the body according to the thickness given theln. lf, however, it is preferred to pivotally connect the front ends of the oblique side springs l to thecross-bar J', the bar J is omitted, or the inner ends of said side springs may connect, pivotally or otherwise, directly to the bottom frame of the body. Yetl prefer the arrangement of parts seen in Fig. 3 for all general purposes. The elevated center portion of the transverse spring-support, Fig. 3, is connected to the rear end of the body by any well-known means adapted to the purpose.

Without limiting my claims to thc precise arrangement of the several parts shown and described, l claim- 1.*111 combination with a front spring-platform for road-wagons,side springs forwardly attached tothe axle at. widely-separated points and obliquely extended therefrom to and connected with a spring-frame, which is rearwardly supported by a king-bolt coupling connecting said frame to the bottom of the body and forwardly sustained upon a transverse spring carried by said axle, substantially as set forth.

2. The combination, in a spring-platform for road-wagons, of side springs obliquely ex tended from the bottom of the body to the axle, and a transverse spring arranged parallel to said axle having its terminal ends suspended therefrom upon shackle-bearings pivotally engaging the outer ends of said side springs, substantially as set forth.

3. The combination, in a front spring-platform for road-wag0ns,of side springs obliquely extended to the axle from a spring-frame sethe bottom of the body to the axle, a transverse spring carried by said axle, and a friction or roller bearing interposed between the elevated center portion of said transverse spring and the bottom of the body, substantially as and for the purpose set forth.

5. In combination with a front spring-platform ot' the character described, the longitudinal central bar E rearwardly extended from the elevated center portion of the transverse spring A and engaging the king-bolt N, substantially as set forth.

(l. In combination with a front spring-platform of the character described, the segmentplate G, secured to the bottom of the body, andthe same being adapted to ride upon a friction or roller bearing F, secured to the elevated center portion of the transverse spring-support A', substantially as set forth.

7. In combination With a front spring-platform of the character described, the longitudinal central bar having its front end constructed to such requisite form as will admit of its rigid attachment to the elevated center portion of the transverse spring A', and to pivotally sustain the roller F, substantially as shown and described.

8. In a rear spring-platform for road-wagons, :side springs having their inner ends secure-d to the bottom of the body and obliquely extended therefrom to the axle, in combination with a transverse spring arranged parallel to said axle, its terminal ends suspended therefrom upon shackle-bearings pivotally engaging the outer ends of said side springs, and having its elevated center portion suitably connected to the rear end of said body, substantially as set forth.
